Buggered if I know.....Premium

Yep. Go to:
C:\Users\username\Documents\My Games\SimBin\RaceRoom Racing Experience\UserData\CarSetups
....Then navigate to the track the set-up is designed for, and plonk it in there.

However.....
Set-ups aren't a silver bullet that'll cure all your woes. Quite the opposite.
A good set-up can give you 2-3 tenths more, but only if you're able to drive it to the limit.
So unless and until you're able to drive the default set-up to its limit, don't even bother with set-ups.
Especially considering that Andreas tends to favor a very loose set-up, so odds are you won't be able to control it.
